Curious about the land down under

I've always wondered about what is there in down under, what is it like to walk upside down that is :D No need to wonder any longer as this is where my travels during fall vacation take me. Somehow I've always explained of why I have chosen a certain area for the next destination so here it comes again: my friend Ave moved to the down under land this year :) Her initial plan is to stay there for a bit, so I figured to go and visit her.

As usual, I got limited time for my travels and as usual I'm going to try to take most out of those few weeks I've got. Planned routes and destinations:

1. Cairns, AU - good 3.5 days
Will arrive there through Stockholm, London and Hong-Kong (please make it so that there are no tropical storms in the area this time, although I will be in Hong Kong airport almost to the date a year later!). Activities should definitely include some adrenalin kick, for an example bit of whitewater rafting? Definitely some ocean activities on a boat to study the Great Barrier Reef and water animals.

2. Brisbane, AU - for about 5 days
Noosa and Rainbow beach here I come with my surfing gear to have the best pancakes in the world :-P ! Hopefully some animal parks will be open during my stay, will check out some sand hills in the ocean (islands made entirely of sand!), the city and the beaches and spend time with my friend, and night clubs and all that this area has to offer.

3. Sydney, AU - 3 days
Of course the city, perhaps some cultural events. Oh and close to Sydney there are mountains called blue ;) and something about a tramway, will see what i can manage there.

4. Tasmania, AU - 3 days
Everything that this little island can offer in 3 days, will be in Hobart area, driving around by bikes and cars like a maniac :-P

5. Christchurch, NZ - 6 days
The city and the most beautiful train ride in the world plus ice climbing on glacier and ocean life with itsy-bitsy dolphins and couple of museums and animal parks hopefully, perhaps even some activities full of adrenalin rush.

6. Auckland, NZ - 6 days
The caves and more Maori culture and Rotorua and Rongitoto and all kinds of fun.

7. San Jose, US - 3 days
Short training course, work related, will try to snap out of the vacation mode and be down to earth for just 2 days.

8. Santa Cruz, US - 4 days
"surf city" is the nickname of this wonderful town in California, so I'll be just surfing.

9. Atlanta, US - 1.5 days
Just to attend U2 concert on the 6th of October in Georgia Dome :)

As of today I will be traveling mostly alone, I got one potential travel companion, but this is to be confirmed still. I'm particularly happy about the U2 concert on the last evening of the trip, tickets to the event are purchased :)
